由於近年來科技發展,傳播訊息變得相當便利,人們可以很容易地在網路上散播訊息,像是商品的廣告,而這種於社群網路上吸引用戶的用法,被稱為病毒式行銷。同時由於廠商總是一次推出許多件同類商品的系列供消費者選擇,該如何有預算限制的情形,替不同價位的商品,找出最適合的代言人,也是個相當熱門的議題。而現今的研究往往沒有考慮到實際的商業環境,消費者對於同一類型的商品,應該需求有限,而不會一味地接收到商品資訊便購買,也就是說消費者的購買能力在過往的相關研究中大多沒有限制。我們考慮到上述的情形,提出了一個嶄新的問題,即為有限預算之多產品利潤最大化(BMPM)問題,考慮消費者的消費能力,要在整體預算有限的情形,替多種商品找到合適的種子使總體的利潤最大化。因此,我們提出了BMPMGreedy演算法以及新的圖架構PWDAG以有效地解決有限預算之多產品利潤最大化問題,並於真實資料集中驗證BMPMGreedy演算法可以有效地最大化利潤。
Due to the development of technology in recent years, the propagation of information has become very convenient. People can easily propagate the information on the Internet, such as product advertisements. This use of attracting users on social networks is called viral marketing. At the same time, because companies always launch a series of similar products for consumers to select from, how to find the most potential influencer for the products of different prices with a seed budget limitation is a very hot topic. However, researches in recent years are often not suitable to the business model in reality because the consumers should have the limited demand for the same type of products. In other words, the purchasing ability of consumers is mostly unrestricted in these related researches. Considering the above situation, we propose a novel problem, called Budgeted Multiple-Product Profit Maximization (BMPM) Problem. Consider the purchasing ability of consumers, we must find suitable seeds for multiple products to maximize the overall profit when the overall budget is limited. Therefore, we propose the BMPMGreedy algorithm and a new graph structure PWDAG to effectively solve this problem. As verified by experiments on real world datasets, BMPMGreedy can maximize the overall profit with high efficiency and effectiveness.
